Summary:PROBLEM TO BE SOLVED: To measure a roll gap with high accuracy for a long time by suppressing a phenomenon in which a foreign substance is stuck while ensuring the safety of a sensor head without changing the length of protrusion of the sensor head from a sensor housing. SOLUTION: A sensor head 11 is constituted of a body 11a and a head portion 11b conically continuing to the end of the body 11a and having a shape in which a top of the head portion is bent like convex for a roll 4 side, and an annular step portion 11e is provided between the lower end of the head portion 11b and the upper end of the body 11a. In the device, the sensor head 11 which has contacted the roll 4 is pressed downward, and when the lower end of the head portion 11b enters the sensor housing 12, a receiving portion A having an annular band-like bottom surface is formed, and a foreign substance x is received in the step difference 11e. When the sensor head 11 moves back to the original position, the foreign substance x is pushed out as it is by the step difference 11e, thereby preventing sticking of the foreign substance.
